Senior Inspector Leung Cheuk-hee, head of Team 1 of Regional Crime Unit, New Territories North, explained the case yesterday that the police had received information earlier that firearms and bullet-proof equipment were in possession and sold through the Internet. After in-depth investigation, the police raided a unit in Xinyao Pavilion, Xinshengyuan, Fanling yesterday morning and seized a pepper pinball pistol, a telescopic stick, two sabers about 30 cm long, three air guns, a bullet-proof suit and 15 gas masks, and arrested the mother and son on the spot.Liang Zhuoxi went on to say that after the police inspected the pepper ball pistol seized for the first time, it was found that there were no pepper balls in the magazine and at the scene, and it was believed that some weapons were successfully sold. At present, the investigation direction includes whether the weapons were directed at the police, how to import them into Hong Kong and where they were sold. The relevant operations are still going on, and more people are not excluded.According to the news, the arrested mother did not rule out being innocent, but because she lived with her son, the police had reasonable reasons to suspect that she was involved in the case, so they arrested her and further investigated whether she was involved in the case; The police also conducted an in-depth investigation into whether anyone intended to use relevant weapons to attack police officers, including firing pepper marbles, to intensify the conflict between the police and the people and achieve a plot to "rekindle the war" in the streets when illegal crowds gathered on the National Day.The young man surnamed Lu, who is suspected of being arrested, is said to be in the first year of the Polytechnic University. Apart from being found to be suspected of selling weapons on social media Instagram, he is also suspected of posting comments advocating secession and inciting violence on the Internet. Therefore, the police security department will also be involved in the investigation.
